Nice tables - wish I had them last night as it looks like I was overdoing it.
What's interesting is that some of these exposure times are less than dithering times. I think I'm going to have to look at optimising the dithering more to not lose as much time.
For LRGB imaging I've started doing LLRGB then dither, repeat. I might have to extend that to something like LLLRRGGBB then dither, repeat.
